Wow. Do you think it has something to do with you being on speed density? I do hope that you are able to get things ironed out and please inform us what the cause is/was. I plan on going speed density as well but I do not want to experience what you are if this is the case.

 

if its caused by speed density then the tune needs worked on more. speed density evo's run smoother then maf. just saying.. so no one gets the wrong idea regarding SD vs maf.

 

Thank you for clearning this up, my friend. I was just making an observation.

 

If it's not SD\tune then I am out of ideas.

 

If its as cold in the cities as it is here right now, that could have something to do with it too lol. Freakin midwest -_-

 

Depends on what one considers "cold." It's been below zero what, 5 days so far this winter? That's cold. 20s-40s like it has been the past week are balmy.

 

Isn't Shane looking at the tune today Revo? I'll be curious what your car does on their dyno.

You should have Shane do a comparo between mine and yours too! I wanna see spool difference between evo X 2.2 and evo 9 2.3L

 

Damn, love this car. That UICP looks nice also!

 

Good luck Revo - still got the MAF so hit me up for that if you need it/when you want it back! I tected you after ProKart day but never got a response, haha. I didn't realize I still had it in the car until I was almost home

 

sick build gl with it

 

It's part throttle and mostly in the higher gears.. saw tuner today and still not resolved.. it has to be SD or this damn BOV. Video and dyno sheets below.

 

Wow that bucks nasty.

 

Its either compressor surge or the BOV, and since you have an antisurge housing.......

 

What BOV is this again?

***Reading the first page is hard lol - I would get a Tial Q and call it a day.

 

Chris and I are working with Turbosmart.. ARGH.. I should have waited and got the Tial Q but it was not in stock at the time. More difficult now since my UICP is MAP custom and I am obviously flanged for the raceport.

Idle vacuum is consistently 15in/hg once the car warms up.. that is at 900-1000rpms.
